[0002] With the continuous development of backlight products, more and more electronic products will use backlight module products, such as mobile phones, tablet computers, car displays, etc. In the production process of backlight module products, the assembly of light strips is directly related to the quality of the product.

[0003] At present, the assembly of light strips is usually done manually. Due to the individual differences in human judgment during assembly, the fitting accuracy cannot be guaranteed. The deviation in fitting accuracy can easily cause assembly deviation, affecting the backlight brightness and thus affecting the shipment of finished products and failing to meet customer requirements. Moreover, manual alignment requires a long time of observing the aiming position, which is not only inefficient, but also has the problem of poor positioning accuracy, making it difficult to assemble the bonded product with other components, reducing product reliability. Utility Model Content

[0004] The purpose of the utility model is to provide a light bar assembly jig, which has a high degree of automation, can reduce manual operation time and labor costs, is suitable for batch production, and ensures the consistency of the assembly position of the light bar and the back panel in batches.

[0005] A light bar assembly jig comprises a positioning seat and a driving component, wherein the driving component is mounted on the upper end of the positioning seat, the positioning seat is provided with a positioning portion, the positioning portion comprises a plurality of bosses arranged at intervals, a groove is formed between two adjacent bosses, the upper surfaces of the plurality of bosses form a supporting surface for supporting the light bar and a back plate, and the driving component can move up and down to move away from or close to the supporting surface.

[0006] In the above technical solution, the positioning seat is used to place the light bar and the back plate, and the driving assembly is mounted on the upper end of the positioning seat. The driving assembly can move up and down to adjust the distance from the positioning seat, so that the assembly process of the light bar and the back plate is more intuitive and easy to operate. The light bar and the back plate are tightly pressed together by the up and down movement of the driving assembly. The overall operation method is simple and efficient, and can ensure a firm connection between the light bar and the back plate. The setting of the boss provides a clear position for the placement of the light bar and the back plate, ensuring the stability of the light bar and the back plate during the assembly process. The upper surfaces of multiple bosses together form a support surface that provides uniform support for the light bar and the back plate, ensuring the flatness during the assembly process. When in use, the light bar is first placed on the support surface to ensure that the light bar is placed stably, and then the back plate is placed on the light bar, and the driving assembly is controlled to move downward to press the light bar and the back plate together. The groove formed between two adjacent bosses provides a channel for gas discharge during the pressing process. The utility model has a high degree of automation, can reduce manual operation time and labor costs, is suitable for mass production, and ensures the consistency of the assembly position of the light bar and the back plate in batches.

[0007] Furthermore, the driving assembly includes a pressing plate and at least one pressing driving member, and an output end of the pressing driving member is connected to the pressing plate to drive the pressing plate to move up and down.

[0008] In the above technical solution, the output end of the downward pressure driving component is connected to the pressure plate, and the downward pressure driving component provides the pressure plate with power to move up and down. The downward pressure driving component can accurately control the up and down movement of the pressure plate to ensure the consistency and stability of the assembly of each light bar and back panel. The pressure plate moves up and down through the downward pressure driving component, realizing flexible and controllable assembly operation of the light bar and back panel.

[0009] Furthermore, a plurality of avoidance grooves are provided on one side of the pressure plate facing the positioning portion.

[0010] In the above technical solution, an avoidance groove is provided on the pressing plate to avoid interference between the pressing plate and the structure on the back plate during the assembly process, thereby ensuring a smooth assembly process and reducing the risk of possible equipment damage.

[0011] Furthermore, a vacuum adsorption hole is provided on a side of the boss facing the driving assembly.

[0012] In the above technical solution, by setting a vacuum adsorption hole on the boss, a vacuum adsorption force can be generated before assembly to firmly fix the light bar on the boss while ensuring the flatness of the light bar, thereby avoiding displacement or offset of the light bar during the assembly process.

[0013] Furthermore, the side wall of the groove is provided with an exhaust hole.

[0014] In the above technical solution, when the light bar is placed on the boss, the vacuum adsorption holes start to work, and the air or gas that may exist between the light bar and the supporting surface is discharged to ensure that the two can fit tightly. The exhaust holes on the side walls of the groove provide an effective gas discharge channel, so that the air or gas can be discharged smoothly, thereby avoiding the formation of bubbles or gaps.

[0015] Furthermore, it also includes a barometer, which is connected to the exhaust hole.

[0016] In the above technical solution, the barometer is connected to the exhaust hole and can display the air pressure at the exhaust hole in real time, so that the operator can intuitively understand the air pressure changes during the assembly process. According to the reading of the barometer, the operator can adjust the position of the light bar in time to ensure that the assembly process is carried out under the optimal air pressure conditions.

[0017] Furthermore, the positioning portion further includes a step groove, and the step groove is arranged adjacent to the boss. When the light bar is placed on the boss, the light bar abuts against a side wall of the step groove.

[0018] In the above technical solution, the contact between the light bar and the side wall of the step groove forms an additional support point, making the light bar more stable during the positioning process, less prone to sliding or shifting, and ensuring the accuracy and consistency of the assembly process. At the same time, the setting of the step groove enables the operator to more intuitively understand where the light bar should be placed. The operator only needs to place the light bar on the boss and make it contact with the side wall of the step groove to complete the positioning without complicated adjustment steps.

[0019] Furthermore, the portion of the positioning portion used for placing the light bar matches the portion of the back plate used for affixing the light bar.

[0020] In the above technical solution, the design of the positioning portion matches the fitting portion of the back panel, so that the back panel can be accurately placed on the light bar, and the light bar can be seamlessly connected with the fitting portion of the back panel, ensuring a tight fit between the light bar and the back panel during assembly, avoiding misalignment or offset.

[0021] Compared with the prior art, the beneficial effects of the utility model are:

[0022] By setting a positioning seat and a driving assembly, and mounting the driving assembly above the positioning seat, the driving assembly can move up and down to approach the positioning seat. The positioning seat is used to place the light bar and the back panel. When in use, first place the light bar on the positioning seat, ensure that the light bar is placed stably, and then place the back panel on the light bar, so that the driving assembly moves downward, and the light bar and the back panel are assembled together.

[0023] The positioning seat includes several adjacent bosses. The setting of the bosses provides a clear position for the placement of the light bar and the back panel, ensuring the stability of the light bar and the back panel during the assembly process. The upper surfaces of the multiple bosses form a supporting surface for supporting the light bar and the back panel. When in use, the light bar is placed on the supporting surface. The supporting surface jointly formed by the upper surfaces of the multiple bosses provides uniform support for the light bar and the back panel, ensuring the flatness during the assembly process.

[0024] A groove is formed between two adjacent bosses. During the assembly process, the air or gas that may exist between the light bar and the supporting surface needs to be discharged in some way to ensure that the two can fit tightly. The setting of the groove provides an effective gas discharge channel, allowing the air or gas to be discharged smoothly, thereby avoiding the formation of bubbles or gaps.

[0035] The light bar assembly fixture of the present invention will be further described in detail below in conjunction with specific embodiments and drawings. The drawings show preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0036] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, where: Figure 1 A schematic diagram of the structure of a light bar assembly fixture provided by an embodiment of the utility model; Figure 2 for Figure 1 A local enlarged schematic diagram in FIG. Figure 3 It is a schematic structural diagram of the light bar and the back plate before assembly according to an embodiment of the utility model; Figure 4 for Figure 3 A local enlarged schematic diagram of the .

[0037] Please refer to Figures 1 to 3 In a preferred embodiment, the light bar assembly fixture of the utility model includes a positioning seat 1 and a driving component 2. The driving component 2 is mounted on the upper end of the positioning seat 1. The positioning seat 1 is provided with a positioning portion 3. The positioning portion 3 includes a plurality of bosses 301 arranged at intervals. A groove 302 is formed between two adjacent bosses 301. The upper surfaces of the plurality of bosses 301 form a supporting surface 303 for supporting the light bar 4 and the back plate 5. The driving component 2 can move up and down to move away from or close to the supporting surface 303.

[0038] The light bar assembly jig provided by the utility model, when in use, the positioning part 3 can position the light bar 4 and the back plate 5, and the driving component 2 can enable the light bar 4 to be smoothly assembled with the back plate 5. The utility model has a high degree of automation, can reduce manual operation time and labor costs, is suitable for batch production, and ensures the consistency of the assembly position of the light bar 4 and the back plate 5 in batches.

[0039] Specifically, the positioning seat 1 is used to place the light bar 4 and the back plate 5, and the driving assembly 2 is mounted on the upper end of the positioning seat 1. The driving assembly 2 can move up and down to adjust the distance from the positioning seat 1, so that the assembly process of the light bar 4 and the back plate 5 is more intuitive and easy to operate. The light bar 4 and the back plate 5 are tightly pressed together by the up and down movement of the driving assembly 2, so that the light bar 4 and the back plate 5 are assembled together. The overall operation method is simple and efficient, and can ensure a firm connection between the light bar 4 and the back plate 5. The setting of the boss 301 provides a clear position for the placement of the light bar 4 and the back plate 5, ensuring the stability of the light bar 4 and the back plate 5 during the assembly process. The upper surfaces of multiple bosses 301 together form a support surface 303, which provides uniform support for the light bar 4 and the back plate 5, ensuring the flatness during the assembly process. When in use, the light bar 4 is first placed on the support surface 303, and then the back plate 5 is placed on the light bar 4, and the driving assembly 2 is controlled to move downward to press the light bar 4 and the back plate 5 together. The groove 302 formed between two adjacent bosses 301 provides a channel for gas discharge during the pressing process. The utility model has a high degree of automation and a good pressing effect, which can effectively improve processing efficiency and ensure product quality.

[0040] Please refer to Figure 2The driving assembly 2 includes a pressing plate 201 and at least one pressing driving member 202. The output end of the pressing driving member 202 is connected to the pressing plate 201 to drive the pressing plate 201 to move up and down. The design of at least one pressing driving member 202 ensures the uniform distribution of the pressing force and improves the assembly quality of the light bar 4 and the back panel 5. The output end of the pressing driving member 202 is connected to the pressing plate 201, and the pressing driving member 202 provides the pressing plate with power to move up and down. The pressing driving member 202 can accurately control the up and down movement of the pressing plate 201 to ensure the consistency and stability of the assembly process. The pressing plate 201 moves up and down through the pressing driving member 202, realizing a flexible and controllable assembly operation of the light bar 4 and the back panel 5.

[0041] Specifically, the pressing plate 201, as the direct action surface of the driving assembly 2, is in direct contact with the back plate 5 and is responsible for applying the pressing force. The pressing driving member 202 usually has precise displacement control and force control functions, which can ensure that the pressing plate 201 applies constant pressure and speed during the pressing process to ensure the assembly quality. It should be noted that the pressing driving member 202 can be a cylinder, an electric push rod, a hydraulic cylinder, etc., and a suitable driving method can be selected according to actual needs.

[0042] Please refer to Figure 2 The side of the pressing plate 201 facing the positioning portion 3 is provided with a plurality of avoidance grooves 2011. The design of the avoidance grooves 2011 ensures that when the pressing plate 201 moves downward to press the light bar 4 and the back plate 5, it will not interfere with the structure on the back plate 5, thereby ensuring the smooth progress of the pressing process and avoiding possible damage or misalignment. At the same time, the design of the avoidance grooves 2011 enables the pressing plate 201 to distribute the pressure more evenly during pressing, avoiding excessive pressure in a specific area, and helping to ensure the uniform fit between the light bar 4 and the back plate 5, thereby improving the assembly quality. Figure 4 As shown, the back plate 5 of this embodiment is provided with a plurality of protrusions 501 on one side facing the driving assembly 2, and the avoidance grooves 2011 are opposite to the protrusions 501. When the pressing plate 201 is pressed down, the protrusions 501 extend into the avoidance grooves 2011, so that the pressing plate 201 is pressed down smoothly, avoiding damage to the back plate 5.

[0043] Furthermore, a vacuum adsorption hole 304 is provided on one side of the boss 301 facing the driving assembly 2. By providing the vacuum adsorption hole 304 on the boss 301, a vacuum adsorption force can be generated before assembly to firmly fix the light bar 4 on the boss 301, while ensuring the flatness of the light bar 4, thereby preventing the light bar from being displaced or offset during the assembly process. Compared with the traditional clamp fixing method, vacuum adsorption is more gentle and will not cause pressure points or stress concentration on the light bar 4.

[0044] At the same time, the side wall of the groove 302 is provided with an exhaust hole 305. During use, when the light bar 4 is placed on the boss 301, the vacuum adsorption hole 304 starts to work, and the air or gas that may exist between the light bar 4 and the supporting surface 303 is discharged to ensure that the two can fit tightly. The exhaust hole 305 on the side wall of the groove 302 provides an effective gas discharge channel, so that the air or gas can be discharged smoothly, thereby avoiding the formation of bubbles or gaps. Since the exhaust hole 305 can effectively discharge air or gas, it also helps to speed up the assembly speed. When the gas is quickly discharged, the back plate 5 can be placed on the light bar 4 more quickly, and the pressing plate 201 can approach or contact the back plate 5 more quickly, thereby shortening the time required for the entire assembly process.

[0045] In some embodiments, a barometer is also included, and the barometer is connected to the exhaust hole 305. The barometer is connected to the exhaust hole 305 to display the air pressure at the exhaust hole 305 in real time, so that the operator can intuitively understand the air pressure changes of the light bar 4 and the back plate 5 during the assembly process. According to the reading of the barometer, the operator can adjust the position of the light bar 4 in time to ensure that the assembly process is carried out under the optimal air pressure conditions. Specifically, Figure 1 and Figure 3 As shown, the present embodiment is provided with a support plate 6, and the downward driving member 202 is provided on the support plate 6. At the same time, a plurality of mounting holes 601 are provided on one side of the support plate 6, and the mounting holes 601 are used to connect with a barometer, and the barometer is mounted on the support plate 6, so that it is convenient for the operator to observe the air pressure of the barometer. If the barometer turns red, the light bar 4 can be manually pushed so that the light bar 4 is flush with the boss 301.

[0046] Please refer to Figure 2 The positioning portion 3 also includes a step groove 306, which is arranged adjacent to the boss 301. When the light bar 4 is placed on the boss 301, the light bar 4 abuts against the side wall of the step groove 306. The abutment between the light bar 4 and the side wall of the step groove 306 forms an additional support point, which makes the light bar 4 more stable during the positioning process and less prone to sliding or shifting, thereby ensuring the accuracy and consistency of each light bar 4 and the back plate 5 during assembly. At the same time, the design of the step groove 306 enables the operator to more intuitively understand the position where the light bar 4 should be placed. The operator only needs to place the light bar 4 on the boss 301 and abut it against the side wall of the step groove 306 to complete the positioning without the need for complex adjustment steps. Through the combined action of the boss 301 and the step groove 306, it can be ensured that the light bar 4 is accurately placed in the predetermined position before assembly, reducing the offset and dislocation during the assembly process, and improving the assembly accuracy and product quality.

[0047] It should be noted that the portion of the positioning part 3 used to place the light bar 4 matches the portion of the back panel 5 used to fit with the light bar 4. The positioning part 3 matches the design of the fitting portion of the back panel 5, so that the back panel 5 can be accurately placed on the light bar 4, and the light bar 4 can be seamlessly connected to the fitting portion of the back panel 5, ensuring a tight fit between the light bar 4 and the back panel 5 during assembly, avoiding misalignment or offset. Precise alignment and high-quality pressing reduce the production of defective products. By ensuring a tight and uniform fit between the light bar 4 and the back panel 5, the defective product rate can be significantly reduced, and the product qualification rate and customer satisfaction can be improved.
